The explosive claim about Kardashian's 2003 sex video with former flame Ray J will apparently be leveled in his divorce case by Humphries's ex-girlfriend Myla Sinanaj, reports TMZ.
Sinanaj – who was subpoenaed by Kardashian's defence team this week – contends that Humphries told her Jenner went so far as to order her daughter to re-record the tape because she didn't feel the first attempt turned out well.
A Kardashian insider denies those claims, insisting that the Keeping Up with the Kardashians star never discussed the scandal with Humphries.
Sinanaj apparently also plans to allege that Humphries was seeking to rush the divorce proceedings earlier this year so the new couple spend the rest of their lives together.
Humphries and Sinanaj's relationship has since soured, with both sides reportedly threatening to reveal embarrassing information about each other in the press.
Kardashian opened up about her divorce from Humphries on Oprah's Next Chapter last week. In the interview, Kardashian said that she believes her estranged spouse is "a good person".
The pair split last year after 72 days of marriage.
